I Can Summon Monsters

A new order has been established on the fertile land, the rules are rebuilt, the world is revived, and a new era is about to come... In this fertile land, the edge of the world is an unreachable iron wall that towers into the sky. Is it a prison or a wall guarding the earth? Until the dawn of a new era, he stood on the iron wall, with the people living in the fertile land behind him, living and working in peace and contentment, and thriving. And when he looked down ahead, it turned out that they were just the tip of the iceberg. It turned out that they were just survivors of the old era... The wasteland is thick with gray fog, alien beasts are rampant, and naked giants hit the iron walls. The world begins to reveal a mysterious corner. How does he walk with the dawn to restore order in the wasteland and let dawn come to the earth again...
